By Ham radio operator and avid CW enthusiast David Finley, N1IRZ. This is the first Morse Code book to detail the Koch method and emphasize the training techniques that are the fastest and most effective for code proficiency. The author
explains how, using Ludwig Koch's training method, prospective hams can quickly grasp code teachings and pass the FCC exams faster. The author, once frustrated over the code-learning process discovered this simple method and used it to
overcome the barrier and upgrade to extra class.
